  3. 10. The electron carrier that is formed during the light-dependent reaction
  4. 11. One of the limiting factors of photosynthesis
  5. 12. Pigments responsible for absorbing green wavelengths in the visible spectrum
  6. 13. One of the ways to measure the rate of photosynthesis
  7. 16. An algae used by Engelmann to demonstrate that different wavelengths of light affect the rate of photosynthesis

Down
  1. 1. A technique to separate pigments by molecule size
  2. 2. The phase of photosynthesis that requires electromagnetic energy from green wavelengths
  3. 3. The process of light splitting a water molecule into 1/2 O2, 2 H+, and 2 electrons
  4. 4. Another name of the light-independent reaction
  5. 5. The conversion of inorganic CO@ to organic molecules such as glucose
  6. 6. Membrane-bound compartments inside chloroplasts and cyanobacteria. They are the site of the light-dependent reactions of photosynthesis
  7. 9. When oxygen reached 1% of current levels, these organisms evolved
  8. 12. The time period when atmospheric oxygen reached levels close to today’s levels
  9. 14. The type of redox reaction that occurs as H2O converts to O2
  10. 15. The colorless fluid surrounding the grana within the chloroplast
